When is SQLNET.ORA read?

During the investigation into SQLNET problems (see previous blog entry) we had cause to change the EXPIRE_TIME in a SQNET.ORA file shared by more than one TNS listener. I could find no documentation that explicitly said when the SQLNET.ORA file was read but all interweb documents seemed to say 'change the file and then restart the listener'. From this we inferred that the lsnrctl only reads the SQLNET.ORA at start up. THIS IS NOT TRUE.
SQLNET.ORA is read on a regular basis by the listener.
